ABSTRACT:
A curing agent package is provided for polymercaptan-terminated polymers comprising selected metal oxides and organonitrogen accelerators and promoters commonly considered as rubber vulcanization accelerators. More specifically, sealant and coating compositions are prepared by curing a mixture comprising a mercaptan-terminated polyether-polyester liquid polymer, a curing agent package of a non-lead metal oxide curing agent and an organonitrogen accelerator or promoter, and, optionally, non-elastomeric materials.
